The Twin Cities just flunked a major national air quality test, and kids are on the front line. The American Lung Association's new State of the Air report hands the metro an “F” for short-term particle pollution and ranks it 39th worst in the country for daily spikes in soot. That failing grade means hundreds of thousands of Minnesota children face a higher risk on poor-air days.
What the numbers say
The 27th annual State of the Air, which used 2022–2024 monitoring data, finds that Hennepin County averaged 4.5 days per year with unhealthy spikes in fine particle pollution. That is the county that pushed the metro into the 39th spot and earned the short-term particle F. According to the American Lung Association, the report also found that roughly 723,418 Minnesota children live in places with unhealthy air exposure. The group noted that, while the metro still passes the federal standard for year‑round particle averages, short-term spikes remain a stubborn problem.
Policy and reaction
"Children deserve to breathe air that won’t make them sick," Jon Hunter, senior director of Healthy Air Solutions for the American Lung Association, wrote in the group's release, urging stronger action to protect kids' lungs. The association pointed to recent federal rollbacks of air protections as a factor that could undermine state and local gains. According to the American Lung Association, about 44% of people in the U.S., roughly 152 million, live in a county with at least one failing grade.
State monitoring expanding
Officials in Minnesota are already trying to fill data gaps at the neighborhood level. The Minnesota Pollution Control Agency awarded $4.83 million in grants to community groups and to an Air Monitoring Network and Education Center (AIRNET) to deploy sensors and help communities track local pollution, the agency says. Per the Minnesota Pollution Control Agency, projects funded include targeted monitoring in neighborhoods with pollution concerns and environmental-justice priorities.
What families should know
Health experts say awareness and simple precautions can take some of the sting out of bad-air days. Check your ZIP code's Air Quality Index and limit strenuous outdoor activity when levels are orange or worse. The US EPA's AirNow site lays out who is most at risk and when children and people with lung or heart conditions should avoid outdoor exertion and use indoor HEPA filtration during smoke or particle events.
